Wouldnt say upgrade. Byrne when healthy was a jet.
Newman's hands aren't as clean and not many have Byrne's agility through traffic.
BUT potentially a good compliment to Docherty and a long term replacement for Simmo, who can now rotate more as an outside mid.
Backline looks very solid now:
FB: Plowman Weitering Simpson
HB: Docherty Marchbank Newman/Williamson
Allows us to scrap Daisy from there too, where I felt his lack of defense screwed us.
